Diligence EV Temperature and Humidity Logger with LCD Display

Diligence EV data loggers are lightweight and small enough to be used almost anywhere. Ideal for many applications including the food, pharmaceutical and chemical industries to monitor sensitive materials in transit or storage. The loggers are also ideal for building services, scientific experiments, production processes and heating, ventilating and air conditioning systems.

Requires dedicated software and a computer interface to download data to a PC - see accessories. Two versions of software are available, EVSW for general use and ideal for HACCP and other quality systems, EVSWPRO which aids compliance with 21CFR Part 11.
